A drug was approved in China

Then it failed clinical trials in the US

No one could figure out why

The answer was hiding in the gut microbiome

Anto Bio’s model helped identify it

99% of the genes in your body aren't yours
They belong to your microbiome
Over two-thirds of drugs are heavily affected by how your gut processes them

But the microbiome data was too noisy. Too messy. Petabytes of it just sitting there

Anto Bio's mission: make the gut microbiome computable for the first time

They're building foundation models that help pharma design drugs that work for more people
